I installed 1.2.0 version and work fine.But i have a problem:I've created 2 contacts: person1 and person2, then I create a new issue from contact menu (in sidebar) with person1, it's OK.Now I want add a person2 to Contact list (in a issue). When I click on "Add" link doesn't show anything. Is this normal?How can i add new contact to contact list?

The contacts migrations is messed up, i had similar and worse problems. At the moment i don't have my papers around i wrote the exact howto workaround, but the summary was to clean up redmine's plugins migrations table from all contact's entries and remove all contacts tables from db and reinstall the complete plugin afterwards. Be aware that you will loose all contacts data on this approach.The problems occours if you migrate down or reisntall sometimes, because there are a lot of errors i migration scripts history.

After manualy deleting all plugin tables, such:

contacts

deals

contacts_deals

contacts_issues

contacts_projects

recently_vieweds

notes

And if you don't have any plugins which use tags

tags

taggings

After should delete all x-redmine_contacts records from shema_migrations table

Now I can see list of contacts and I can add new one.But I can not see contact: I got Error message: Expected /usr/local/lib/ruby/gems/1.8/gems/acts-as-taggable-on-2.0.6/lib/acts_as_taggable_on/acts_as_taggable_on.rb to define ActsAsTaggableOn::ActsAsTaggableOn
